Short answer: the SVS SB17-Ultra R-Evolution, if you are buying new. The SVS SB13-Ultra measures as well as it (#96 vs #102 of 143 subwoofers, 4.1/5 vs 4.1/5) but is discontinued, so only consider it used; the SVS SB17-Ultra R-Evolution is still sold new at $2,699.
The case for the SVS SB17-Ultra R-Evolution: A flagship sealed 17 inch subwoofer with a very powerful amplifier, app control and automatic room calibration. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Why pick the SVS SB13-Ultra: A compact sealed 13.5 inch subwoofer with punchy, tight bass for music and movies, now discontinued but worth buying used. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the SVS SB17-Ultra R-Evolution if you want one new; the SVS SB13-Ultra is discontinued, so only look for it used.
About the ratings: the SVS SB17-Ultra R-Evolution’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.9 to 4.3, so this verdict could change once it is measured.
